Objective: To analyze the level of resilience and its influencing factors in the young and middle-aged patients with type 2 diabetes mellitus ( T2DM ), so as to provide reference for optimizing mental interventions for the patients. Methods: The young and middle-aged patients with T2DM from September 2019 to September 2020 in Hangzhou First People's Hospital, affiliated to the Medical School of Zhejiang University, were selected as the subjects, the general information questionnaire, Perceived Social Support Scale ( PSSS ) , Conner-Davidson Resilience Scale ( CD-RISC ), Diabetes Distress Scale (DDS) and Diabetes Management Self-efficacy Scale ( DMSES ) were used to investigate, the multivariate linear regression model was used to analyze the influencing factors for resilience in young and middle-aged patients with T2DM. Results: A total of 250 questionnaires were distributed and 238 valid questionnaires were recovered. The effective recovery rate was 95.20%. Among 238 patients, 142 cases ( 59.66% ) were males and 96 cases ( 40.34% ) were females; 168 cases ( 70.59% ) were 45-59 years old. The CD-RISC score was 70.49±12.81, PSSS score was 63.70±10.90, DDS score was 2.14±0.87, and DMSES score was 130.22±38.49. The results of multivariate regression analysis indicated that educational level, average monthly family income, fasting blood glucose, self-efficacy, social support and diabetes distress were the influencing factors for resilience of young and middle-aged patients with T2DM ( P<0.05 ). Conclusion The level of mental resilience in young and middle-aged patients with T2DM is mainly related to the level of education, monthly family income, blood glucose control, diabetes distress, self-efficacy and social support.

BACKGROUND:Many experiments have demonstrated that tissue engineering scaffolds prepared by polymer materials alone or biomaterials cannot meet the requirement of tissue engineering research.
OBJECTIVE:To evaluate biological characteristics and cel affinity of poly(hydroxybutyrate-co-hydroxyoctanoate)/col agen composite scaffold.
METHODS:Tissue engineering scaffolds were prepared by combination of poly(hydroxybutyrate-co-hydroxyoctanoate) and col agen at different proportions (2%, 4%, 6%, 8%and 10%) using solvent casting/particulate leaching method. Inner structure and apertures were observed by scanning electron microscope, and the porosity was determined by liquid displacement method. Rabbit chondrocytes were co-cultured with poly(hydroxybutyrate-co-hydroxyoctanoate)/col agen composite scaffold and poly(hydroxybutyrate-co-hydroxyoctanoate) scaffold. Growth curve of cel s was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, and cel adhesion on the scaffolds was observed by scanning electron microscope.
RESULTS AND CONCLUSION:The pore size and porosity of the composite scaffold were about 200μm and (85±2)%, respectively. The cel affinity dynamical y increased with the increasing of proportion of col agen. Compared with the poly(hydroxybutyrate-co-hydroxyoctanoate) scaffold, the poly(hydroxybutyrate-co-hydroxyoctanoate)/col agen composite scaffolds are better to improve cel adhesion and proliferation, with favorable cel ular affinity.

Objective To investigate the prevalence of high urine albumin-to-creatinine ratio (ACR) among health check up population and evaluate the potential predictors for ACR. Methods A cross-sectional study was conducted among health check up population in the Zhongshan Hospital during 2015. Potential participants completed urine ACR test,body mass index (BMI) and blood test. ACR level was divided into two groups according to the K/DOQI recommendation:ACR Group(male:ACR≥17 mg/g;female:≥25 mg/g), Normal Group (male:ACR<17 mg/g;female:ACR<25 mg/g). Univariate and multivariate logistic regression models were performed to evaluate the associations of ACR with potential predictors (including age,sex,over-weight or obesity,hypertension,glucose metabolism disorders, hypertriglyceridemia,hypercholesterolemia,high low HDL-C and hyperuricemia). Result Totally 670 people from the health check up population were screened for ACR test, 54 cases were positive, the prevalence was 8.1％. Age, BMI, waist-to-height ratio, SBP, DBP, blood sugar and uric acid had statistical significance between Normal group and ACR group[Age 47.62 ± 11.29 vs. 53.83 ± 11.93, t=-3.858, P<0.01;BMI (24.05±3.12) kg/m2 vs. (24.94±3.49) kg/m2, t=-1.982, P<0.05;waist-to-height ratio 0.51±0.52 vs. 0.53 ± 0.06, Z=-2.146, P<0.05; SBP (mmHg, 1 mmHg=0.133 kPa) 115.31 ± 15.59 vs. 130.91 ± 23.66, t=-4.755, P<0.01;DBP(mmHg) 72.31 ± 9.16 vs. 80.02 ± 9.81, t=-5.897,P<0.01;blood sugar (mmol/L) 4.64 ± 1.20 vs. 5.57 ± 2.77, t=-2.466, P<0.01;uric acid (μmol/L) 362.99 ± 92.80 vs. 397.76 ± 95.62, t=-2.633, P<0.01]. Age, hypertension, glucose metabolism, HDL reduction were risk factors for urinary albumin/creatinine ratio. In the multivariate logistic regression model, hypertension status was found to be associated with ACR positive [odd ratio (OR): 2.843, 95％ confidence interval [CI, 1.472-5.493, P<0.01], glucose metabolism disorders (OR, 2.132, 95％CI, 1.042-4.365, P<0.05). As the number of risk factors increases, the rate of positive of ACR showed marked increase, comparing persons with no risk factors to those with four or more risk factors , the OR value rose up to 18.281. Conclusion Hypertension and glucose metabolism disorder are risk factors of chronic renal dysfunction. With the increase of risk factors, the rate of positive of ACR was higher. ACR test is recommended routine screening for people over the age of 50.

Objectives To analyze the diagnosis and management of steroid-resistant nephrotic syndrome (SRNS) accompanied with irreversible leukoencephalopathy in children. Methods The clinical, laboratory and imaging data were retrospectively analyzed in a SRNS child accompanied with irreversible leukoencephalopathy. A literature review was performed. Results After clinical diagnosis of SRNS, glucocorticoid, immunosuppressant, and hemodialysis were administrated for 10 months. During the course of treatment, the seizures, visual problems, and hypertension were repeatedly occured. The cranial MRI showed bilateral occipital parietal lobe hyperintensity and right frontotemporal lobe hyperintensity on T2-weighted imaging and bilateral occipital parietal lobe hypointensity on T2-Flair imaging, which indicated that encephalomalacia was accompanied with gliosis. Conclusions A variety of reasons may induce leukoencephalopathy in children. The accompanied irreversible leu-koencephalopathy should be strongly considered in management of SRNS.

Objective:To explore the three long non-coding RNA (long non-coding ribonucleic acid, the expression of lncRNA NR_002578, NR_038264 and NR_046252) in peripheral blood mononuclear cells (PBMCs) of patients with primary gout arthritis (GA) and their clinical value.Methods:Peripheral venous blood, clinical data and laboratory data were collected from 60 gout patients (including 30 AG patients in acute stage and 30 IG patients in intermittent stage) and 50 healthy subjects (HC group). Quantitative reverse transcription PCR (RT-qPCR) was used to detect the expression levels of PBMCs of 3 lncRNAs in GA and HC groups, and the differences of 3 lncRNAs expression levels in different groups were compared and the correlation analysis was conducted with clinical indicators. Receiver operating characteristic curve (ROC) was constructed to evaluate the possible efficacy of lncRNAs in gout diagnosis. The measurement data conforming to normal distribution were tested by t test or variance analysis, and non-normal distribution were tested by Mann-Whitney U test or Kruskal-Wallis H test. The comparison among the three groups was conducted by SNK. Results:① The expression of NR_002578 in GA was significantly lower than that in HC [60.2(16.8, 100.1)×10 -3vs 149.5 (92.6, 221.8)×10 -3, Z=-5.75, P<0.001], subgroup analysis showed that the expression of NR_002578 in AG was significantly lower than that in IG and HC [34.3(8.6, 72.8)×10 -3vs 88.3(47.7, 109.6)×10 -3vs 149.5(92.6, 221.8)×10 -3, H=40.12, P<0.001], and lower in IG than that in HC ( P<0.001). The expression of NR_046252 in GA was significantly higher than that in HC [6.5(2.1, 21.5)×10 -3vs 2.1(1.2, 3.5)×10 -3, Z=-4.21, P<0.001]. The expression of NR_046252 in AG and IG were higher than that of the HC group [6.3(2.0, 12.0)×10 -3vs 7.2(2.4, 30.6)×10 -3vs 2.1(1.2, 3.5)×10 -3, H=21.33, P<0.001], but there was no significant difference between the AG and IG group ( P>0.05). ② Spearman correlation analysis showed that NR_002578 expression was negatively correlated with erythrocyte sedimentation rate (ESR) ( r=-0.29, P=0.024)and hypersensitive C-reactive protein (hs-CRP) ( r=-0.35, P=0.006) in gout patients. ③ The areas under ROC curve of NR_002578 and NR_046252 for diagnosing gout were 0.819 and 0.750, respectively. Conclusion:The abnormal expression of NR_002578 and NR_046252 in gout patients suggests that NR_002578 may be involved in the pathogenesis of gout.
